I have been trying to explain this to a technician who is not very informative, but as I like him, I write the procedure here and we systematize the free consultancies.
You have a background image, but you want to hide part of it for printing and presentation purposes. It has Microstation V8.5
Before I talked about how to do something this with Descartes, but for purposes of merging several raster and save them as new images. In this case, it is not what is needed exactly because it is only for visualization purposes, it is not intended to cut the images.
So the option is to do it using the raster clip.
In the Raster manager, select the images you want to hide and the "Edit / Clip"
Then a little window pops up asking:
... you're wanting to clip, you can tell me from that ???, then you should choose the cut method and mode.
1. By means of an element
You can have a drawn object, which is a closed figure such as a polygon. So we chose the Element option, and then Clip Boundary; this is the result.
Once you have chosen the type of object (method) that you hide, you define whether you want to hide the inside, or the edge. For this are the two options:
- Clip Mask, hide it inside
- Clip Boundary, hide the outside
2 By means of a painting
In this case, it is possible to make a table without having to have an object, for this you choose "Block" and mark the box with the mouse. Then a new click to see the result.
3. By means of a fence
If there is a fence, it can have "flood" properties and it can be practical for complex figures or boundaries that are not a closed shape. First the fence must be made, and so it can be chosen from the "Method" option.
The following image shows different clips made, the red one with the "Element" method, the one crossed with "Fence", the others with "Block". And everyone can live together, the image is the same.
This fence is very practical, because in the Microstation XM or V8i versions the fences can be saved as if they were models.
There is also the "modify clip" option that allows you to edit the vertices, just like I did with one of the boxes. To delete one of the clips, use "edit / unclip" and you can select individually or all the boundaries.
Step by step
Summary of the procedure for non-technological; in this case, there is an image downloaded from Google Earth, and you want to cut it with respect to an 1 map: 10,000
1 Call the raster
2. Touch it in the raster manager
3. Edit / clip
4. Select Method "Block"
5. Select Mode "Clip Boundary"
6. Make the box with the mouse: To activate the snap is pressed ctrl + shift
7. Click on the screen.
Because of the fact that this quadrant it is not exactly a rectangle, you can choose "edit / modify clip" and the ends are sent to the corresponding equines, always with the activated snap of the ctrl + shift
Man, I hope that even a refreshment will fall when they come here ... because this is in the readme.
